Mass of isotopes are not integers.
Isotopes of the same element have the same number of protons (atomic number) but differ in number of neutrons (hence atomic masses).
Isotopes
They are called isotopes. eg we have different isotopes of carbon
See the link below for the masses of all radium isotopes.

Masses.
Isotopes. eg U235 and U238. Both Uranium, atomic number 92, bur different isotopes.
They are called isotopes. They have different mass nmbers because they have a different number of neutrons.
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
they're called isotopes.
Different atoms of the same element possessing different atomic masses but having same atomic number are known as Isotopes. Since the isotopic atoms have the same atomic number, they must contain an equal number of protons. As their atomic masses are different, there must be a difference in the number of neutrons they possess. They will show similar chemical properties but their physical properties will be different due to different masses.
